In industrial applications, many loads have strict requirements for the output characteristics of inverters. In addition to variable frequency and adjustable voltage, the output voltage fundamental wave should be as large as possible and the harmonic content should be as small as possible. A square wave output inverter composed of thyristor components without self turn-off […]

Below is a detailed introduction to common UPS faults and their solutions. 1. When the mains power is available, UPS will issue a power outage alarm. Possible reasons: 1) The mains power input circuit breaker tripped. 2) Poor contact of input communication line. 3) The input voltage of the mains power is too high, too

A voltage regulator is a device designed to automatically maintain a constant voltage, and its main functions include the following aspects:

（1） Compensation principleThis compensating voltage regulator is based on the principle of electromagnetic induction to achieve stable voltage regulation. When the input voltage changes, the compensation winding inside the voltage regulator will automatically adjust the magnetic flux according to the voltage fluctuation. By changing the number of turns or current magnitude of the compensation winding,

The working principle of an inverter is to high-frequency switch DC power through electronic switching devices, forming a pulse width modulation (PWM) signal, and then convert the pulse signal into AC power through a filter. The basic structure of an inverter includes DC power supply, switching devices, control circuit, and output filter.

Performance and characteristics of rectification and voltage regulation power supplyRectification and voltage stabilization are commonly used concepts in the field of electronics to control the effectiveness and stability of power output voltage. Rectification converts AC power from a power source into DC power and converts it into a stable output current; Voltage stabilization is achieved

1. Firstly, the packaging of the battery should be checked for damage, and then the packaging should be carefully opened to check whether the batteries are ingood condition one by one; And check the factory date of the battery to determine the time when the battery needs to be recharged when it is put into

Some UPS units use watts (W) or kilowatts (kW) to represent their output power, such as 500W 1kw or other UPS uses volt ampere (A) or kilovolt ampere (kVA represents its output power, such as 3000VA, 5kA, etc. The general conversion relationship between VA and W is: watts are 0.8 times the volt ampere, such

Firstly, let me briefly explain the function of the inverter. Inverter is an electronic device used to convert direct current into alternating current through the combined action of inverter bridge, control logic, and filtering circuit.Photovoltaic inverters are important equipment in the process of solar power generation. Solar cells generate direct current under sunlight, and the

UPS is an abbreviation for Uninterruptible Power System, which emerged with the birth of computers and is one of the commonly used peripheral devices in computers. In fact, UPS is a constant voltage and rated uninterruptible power supply that contains energy storage devices and is mainly composed of inverters. In its early stages of development,
